ALBERT LEDUO, OF PARIS, FRANCE.

SPECIFICATION forming part of Letters Patent No. 231,724, dated August 31, 1880, Application filed June 16, 1880. (No model.) Patented in France December 29, 1879.

To all whom it may concern Be it known that I, ALBERT LEDUO, of Paris, France, have invented a certain new and useful Improvement in IroningApparatus for Use in Finishing Felt Hats, of which the following is a specification.

The invention has for its object the ironing mechanically of hats of any shape by means of an apparatus for holding and revolving the form on which the hat is placed and a sadiron holder, to the end thatthe work may be hastened and at the same time a uniform pressure of iron on the hat be obtained. To accomplish these results the skill of the operator has been heretofore relied upon.

The apparatus for revolving the form and the sad-iron holder are of special construction,

whereby they are adapted to effectthe ends sought.

The invention and the manner of carrying it into effect, in order that the same may be fully understood, will now be described, in connection with the accompanying drawings, which form a part of this specification.

Figures 1, 2, and 3 illustrate, in section, plan, partly in section, and end view, respectively, the mechanism for holding and revolving the form. Figs. 4 and 5 are a section and a plan of the sad-iron holder, and Figs. 1, 6, 7, 8, 9, and 10 detail views.

In Fig.1 the apparatus, as shown, is turned to the right, so that the platform appears vertical instead of horizontal, as it normally is, and as shown in Figs3.

Upon a supporting-frame surmounted by a table or platform, A, is placed a bracket, B, in hearings in the arms of which the hollow arbor E is supported. On this shaft, between the arms, are the'two loose pulleys O O and an intermediate fixed pulley, D. Through the hollow arbor E extends a shaft, F, having on one of the projecting ends a screw-thread, on which the nut G turns, and also a hand-wheel, H, keyed onto the shaft, and on the other end an oblong piece, a. The nut G is provided with handles, to be grasped by the operator. The form I is provided at the bottom with a cavity, 0, and a plate, 0, extending across the face of said cavity, and provided with an oblong opening, I). To secure the form I so that it will be revolved with the arbor E, the 0blong piece a at the end of the shaft, F is made to pass through the opening I) in the plate 0, the shaft F is moved a quarter-turn, so as to bring the projecting ends of the piece a under or behind the plate 0, and the nut G is screwed down tight. A small pin or projection, (7, Figs. 1 and l, on the shaft F, movable in a cavity, (1, is used to regulate the movement of said shaft in. the arbor E. To remove the form the nut G is unscrewed and the shaft F turned so as to bring the oblong piece a opposite the opening in the plate 0.

In connection with the pulleys on the arbor- E two beltsa plain and a crossed belt-are used. Their position is changed as may be required to revolve the arbor E in one direc tion or the opposite, or allow it to remain stationary, by means of abeltshifter constructed as follows: Supported in suitable bearings f under the table A is a shaft, 0, upon one end of which is fixed an endless screw, J, and at the other a hand-crank or operatingdcvice, L.

Upon a stationary rod, h,is a slide, 71 of which i a projection, g, is engaged by the thread of the .endless screw J. The slide is prevented from turning by arms resting at the outer ends upon guides It is surmounted by an annular disk, K, pierced with holes is. In one of the holes k is fixed a fork, M, (seen in plan, Fig. 2, and elevation, Fig. 3,) through which the endless belt l passes. In Fig. 3 the fork M occupies the positio indicated in full lines when the sides of the belt are parallel, and that indicated in dotted lines when the belt is crossed.

Each of the loose pulleys G 0 is double the width of the fixed pulley D, and the belts l l are of a width corresponding to the fixed pulley. With the belts disposed as represented in Fig. 1 the direction of revolution can be changed by turning the crank L, so that by means of the endless screw J the annular disk K is moved and the belt 1 shifted to the pol ley C and the belt Z to the pulley D.

To stop the machine the annular disk K is moved the distance required to shift the belt lto pulley U and leave the belt I on pulley 0. Both belts now run on loose pulleys and the machine is stopped.

The sad-iron holder will now be described, reference'being had more particularly to Figs.

4 and 5. It is composed of a bed-piece, P,

which is placed upon the table A, and an ad- 2 seems;

,justable part, Q, at the sides of which are two handles, 19.

In the interior of the bed-piece P is a rack, q, with which a pinion, q, engages. The pinion is journaled in hearings in the part Q, or turns on a shaft fixed in said part, and is revolved by means of an endless screw, It, carried at the lower end of the upright shaft 1", which is supported in the elevated portion 0*, to and is provided at its upper end with a handwheel or operating device, 1".

The rack and pinion are partially shown in full lines in Fig. 4, and the remainder indicated by the dotted lines.

The extremity s of the adjustable part Q, is provided on each side with a small angularshapcd piece, .9, which fits into a suitablyshaped recess, .9, in the llOl'l-SUDPOI'E S. Between the latter and the portion r of the part Q is placed a spiral spring, 2, surrounding the extensible bar T, formed in two parts, sliding on each other, and provided with heads t, for

inclosing the ends of the spring 25.

A roller, a, carried at the end of the bedpiece P, moves in an angular guide, U. The curvature of the exterior of the roller and of the interior of the bend in the guide is the same. The form of the guide is shown bestin Fig. 2, and in small Figs. 6 to 10.

In order to adjust the guides to difl'erent positions suited to different forms of hats it passes under a yoke, V, sliding in a slot, 00, Figs. 2 and 6, in the table A, and is fastened by a screw, w, working in a screw-threaded 5 opening in the upper part of the yoke V, and a piece, 3/, Fig. 1, with which the lower end of the said screw is connected. The guide can thus be adjusted lengthwise of the slot no and also in the required angular position.

Thepositions of a right-angled guide relative to the hat to be ironed are shown in Figs. 6, 7, and 8.

In Figs. 9 and 10 the guide has an obtuse angle and is thus adapted to Tyrolieu hats.

The manner of using the apparatus will be readily understood.

The hat with its form having been fastened so as to revolve with the arbor E, the guide U is adjusted to the position shown in Fig. 6 0 for a hat of the form indicated, and the roller a is placed in the guide. The workman then, by turning the wheel 0', moves forward the iron till it bears on the hat with the desired pressure. The hat being revolved gives, on account of its oval shape in cross-section, a rocking movement on the pointss to the iron. The pressure is uniformly maintained by the spring t. The workman then moves the iron-holder so that the roller a follows the part 1 of the guide to the bend 2, and thence along the part 3 until the point 4, which is the center of the hat, is reached. It will be seen that in'this way there is obtained a uniform pressure, which can be regulated at will by moving the iron-support toward or away from the hat.

The forms, proportions, and materials employed and also the disposition and construction of parts may be changed without departing from the spirit of the invention.

The belt-shifter described could be used in other machines, and also other mechanism than that indicated could be used for imparting revolution to the form I, although it is preferred to employ the devices shown.

Having now fully described my said invention and the manner in which the same is or may be carried into effect, what I claim, and desire to secure by Letters Patent, is-

- 1.. An ironing-machii'ie comprising, in combination with a revolving support, a sad-iron holder and devices for mechanically holding the iron against the hat with a yielding a'djustable pressure, substantially as described.

2. The combination of an arbor turning in bearings with a form and devices,'as described, 7

for simply and rapidly securing said form to the aforesaid arbor, as indicated.
